Gibraltar DCIH40-76 Heavy-duty Die Spring Red

Product Description

The GIBRALTAR DCIH40-76 is a heavy-duty die spring engineered for use in stamping dies, punch presses, and industrial tooling applications. It features a 1.5-inch hole diameter, a 0.75-inch rod diameter, and a 3-inch free length. The spring is wound from chromium alloy steel with a trapezoidal wire profile, which provides a higher load capacity per unit of compressed length compared to round wire designs. It carries a maximum deflection load of 1334 pounds at 1.0 inch of travel, making it suitable for high-cycle industrial press tooling. Toolmakers, die setters, and maintenance machinists are the primary installers for this component.

This die spring is intended for use in metal stamping and forming dies, injection mold components, and industrial fixturing where consistent, repeatable spring force is required. The red color designation indicates a heavy-duty load rating under both NAAMS and ISO 10243 standards, which makes cross-referencing with other compliant spring series straightforward. It is suited for both new die builds and replacement service in existing tooling setups where a NAAMS- or ISO 10243-compliant heavy-duty spring is specified.

Key Features

• Heavy-duty load rating: 1334 pounds maximum deflection load at 1.0 inch maximum deflection
• Trapezoidal wire cross-section for higher load density compared to round wire springs
• Chromium alloy steel construction for fatigue resistance under high-cycle press conditions
• Red color coding per NAAMS and ISO 10243 heavy-duty classification for easy identification
• Compliant with NAAMS, ISO 10243, and manufactured under ISO 9001:2015 registered quality standards
• Spring rate of 1334 pounds per inch for predictable, linear force output

Compatibility

Designed as a NAAMS- and ISO 10243-compliant heavy-duty die spring suitable for use in stamping dies, mold bases, and industrial tooling wherever a 1.5-inch hole diameter, 0.75-inch rod diameter, 3-inch free length heavy-duty spring is specified.

Installation Notes

Die spring replacement and installation should be performed by a qualified toolmaker or die setter with the press locked out and all stored energy safely released per applicable OSHA lockout/tagout procedures. Inspect the rod and bore for wear or misalignment before installing a replacement spring, as side loading significantly reduces service life. Do not compress the spring beyond its rated maximum deflection of 1.0 inch, as operating at or beyond solid height will cause premature failure. Consult the die design documentation for proper preload and seating requirements.
